FIELD: engines and pumps.
SUBSTANCE: proposed engine comprises body with solid-propellant multigrain charge arranged between support grates, two gas-communicated nozzles of different diameters of throat and igniters with pyrotechnical compound equipped with exploder. every said igniter is fitted in one of ante-nozzle cavities arranged on every side from charge support grates. Weight of igniter on nozzle side of smaller throat is larger than that of exploder of opposite igniter and/or exploders of igniters feature different energy capacity. Energy capacity of the exploder on smaller throat nozzle side is larger than that on opposite side.
EFFECT: decreased disturbances of the rocket end jettisonable structure.
